Forged through multiple years of lockdown, the M021 focused on quality-of-life improvements that enable the team to keep the strong platform of what worked and make overall testing easier. The M021, in comparison to the M019, features a rear access accumulator which enables easy and convenient access to the accumulator without the requirement of multiple personnel. The M021 now newly employs a pushrod suspension system that enables the ability to have more control over tune-in testing.
